Hi, SIP Presence Event Package RFC( 3856 ) says that From and To of a SUBSCRIBE cannot be a TEL URI:
Section 5. SUBSCRIBE messages also contain logical identifiers that define the originator and recipient of the subscription (the To and From header fields). These headers can take either a pres or SIP URI. Why? Why is valid a PRES URI but not a TEL? -- Iñaki Baz Castillo <[EMAIL PROTECTED]> _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
